Johnson line American bulldog is a GREAT dog . Large enough (different bloodlines will range from 95 lbs up to 150 lbs) temperment is good , and drive is all you can handle , but not too much . My AB is 100% johnson line with alot of Mean machine blood . He is not quite 11 months , 97 lbs , 25 inches at shoulder . Get along well enough with my Feist hound(jack russel/rat terrier cross) who is 12 lbs, blind in one eye and rules the roost wwith an iron fist . The AB deffers to her even at food bowl, but does chase our cat and pin him without hurting him . Mr Johnson(RIP) who rescued the breed from extiction had a brush fire near his house , 2 of his AB's were fighting the fire , tearing down trees and alerting his family so they could clear the kennels and house . They were both BADLY burned , but lived . THAT is protection that MOST animals would not atempt .You cant go wrong with an AB of the JDJ american bulldog . If you have ANY questions about these dogs please e-mail me and I will get you some info on breaders close to you who can help/show you their dogs . ....[br][link={e_FILE}public/1251946398_17540_FT50595_miscpup_136.jpg][img:width=450&height=338]{e_FILE}public/1251946398_17540_FT50595_miscpup_136_.jpg">[/link][br][br][link={e_FILE}public/1251946398_17540_FT50595_jdj_show_09_012.jpg][img:width=450&height=338]{e_FILE}public/1251946398_17540_FT50595_jdj_show_09_012_.jpg">[/link][br]
